I've recently found out that, after installing my system and being satisfied with it for weeks, that it will not play multiple sounds at once properly, especially while changing volume. When I play a youtube video (or any source of sound at all from Firefox), the sound from the video will be boosted to maximum and will become extremely scratchy and interfered. As I don't know where to start and have no idea how to operate Linux audio (I use both ALSA and PulseAudio globally), I don't know what data I should dump to diagnose this situation.

Playing any sound concurrently with 2 applications causes the distortion and elevated sound level of at least one of them. I have reinstalled alsa-libs/alsautils/alsamixer/alsaequal twice with stock CFLAGS, also no effect.

My theory is that alsa doesn't properly mix the sounds and when volume is raised or lowered. I wouldn't know a thing about audio in linux so help please _________________Specs: AMD FX-6100|ASUS M5A97 AM3+|XFX AMD Radeon HD 6870|1TB 7200RPM/500GB 7200RPM|8GB DDR3 1600MHz
